Bobs car gets 23 miles per gallon of gas. If bobs car is traveling at a constant rate of 69 miles per hour, how may gallons of gas will his car use in 40 minutes?
To calculate the number of gallons of gas Bob's car will use in 40 minutes, we need to follow these steps:
Step 1: Convert 40 minutes to hours. Since there are 60 minutes in an hour, dividing 40 minutes by 60 will give us the equivalent in hours:
40 minutes ÷ 60 = 0.67 hours (rounded to two decimal places)
Step 2: Calculate the total distance traveled in 0.67 hours by multiplying the speed (69 miles per hour) by the time (0.67 hours):
69 miles per hour × 0.67 hours = 46.23 miles (rounded to two decimal places)
Step 3: Determine the number of gallons of gas used by dividing the distance traveled (46.23 miles) by the car's fuel efficiency (23 miles per gallon):
46.23 miles ÷ 23 miles per gallon = 2.01 gallons (rounded to two decimal places)
Therefore, Bob's car will use approximately 2.01 gallons of gas in 40 minutes.
To find out how many gallons of gas Bob's car will use in 40 minutes, we need to follow these steps:
Step 1: Convert the time from minutes to hours.
Since 1 hour has 60 minutes, we divide 40 minutes by 60 to get the equivalent time in hours.
40 minutes ÷ 60 = 0.67 hours
Step 2: Calculate the distance traveled during that time.
The formula for distance is: distance = speed × time
Given that the car is traveling at a constant rate of 69 miles per hour and the time is 0.67 hours:
distance = 69 miles/hour × 0.67 hours = 46.23 miles
Step 3: Determine the number of gallons used.
The car gets 23 miles per gallon. So, we divide the distance traveled by the car's fuel efficiency:
Number of gallons = distance ÷ fuel efficiency
Number of gallons = 46.23 miles ÷ 23 miles/gallon = 2.01 gallons
Therefore, Bob's car will use approximately 2.01 gallons of gas in 40 minutes.
